Assessment of PPG & PAT to Detect Upper Airway Obstruction in Patients With Obstructive Sleep Apnea

April 9, 2013 updated by: Sotera Wireless, Inc.

Assessment of a New Photoplethysmographic (PPG) Method and a Pulse Arrival Time Method to Detect Upper Airway Obstruction in Patients With Obstructive Sleep Apnea Hypopnea Syndrome (OSAHS) in a Sleep Laboratory

The goal of this study is to collect raw waveform data for two separate noninvasive methods, both of which may be useful for the assessment of upper airway obstruction.
